Due to its extreme latitude, Stokmarknes experiences polar day (also known as the midnight Sun) during the summer and polar night during the winter. These are periods of time in which the sun is continuously above or below the horizon for more than one day. The precise start and end dates of polar day and night vary from year to year and depend on the precise location and elevation of the observer, and the local topography.
In the summer in Stokmarknes during 2017, the Sun is continuously above the horizon for 1.9 months, rising at 1:07 AM on May 23, and not setting again until 12:42 AM on July 21.
In the winter in Stokmarknes during 2017, the Sun is continuously below the horizon for 1.1 months, setting at 12:13 PM on December 3, and not rising again until 11:47 AM on January 8.

Sunrise & Sunset with Twilight and Daylight Saving Time
We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.
The perceived humidity level in Stokmarknes, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, remaining a virtually constant 0% throughout.

This report illustrates the typical weather in Stokmarknes, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Temperature and Dew Point
There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Stokmarknes.
For each station, the records are corrected for the elevation difference between that station and Stokmarknes according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
The estimated value at Stokmarknes is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Stokmarknes and a given station.
The stations contributing to this reconstruction are: Evenes (43%, 72 kilometers, east), Andøya Andenes Airport (29%, 95 kilometers, northeast), Bodø Airport (15%, 146 kilometers, south), and Rost Flyplass (13%, 165 kilometers, southwest).
All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.
All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.
